I have been trying to get all the interface list and ip addresses on my
AIX box.....but it doesn't seem to work.......also I am unable to get
the stateless ip addresses for IPV6 ....any help or suggestions how to
do it........Below is my code.......


#include <sys/types.h>
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <netdb.h>
#include <netinet/in.h>
#include <unistd.h>
#include <net/if.h>
#include <arpa/inet.h>
#include <stdio.h>
#include <string.h>

#define num 5
int n;

int main(){
int sd,err,ifsize;
struct ifconf ifc;
struct ifreq *ifr;
struct ifreq ifreq;
struct sockaddr_in *sa;
char *cp,*i;
sd=socket(AF_INET6,SOCK_STREAM,0);

ifsize=num*sizeof(struct ifreq);

ifc.ifc_buf=(char *)malloc(ifsize);
ifc.ifc_len=ifsize;
err=ioctl(sd, (int)SIOCGIFCONF, (caddr_t)&ifc);
n=(ifc.ifc_len/sizeof(struct ifreq));
printf("Interfaces = %d\n",n);
i=ifc.ifc_len+ifc.ifc_buf;

for(cp=ifc.ifc_buf;cp<i;cp+=sizeof(ifr->ifr_name)+sizeof(ifr->ifr_addr)){
ifr=(struct ifreq *)cp;
ifreq=*ifr;
sa=(struct sockaddr_in *)&ifreq.ifr_addr;
printf("interface name=%s
%s\n",ifreq.ifr_name,inet_ntoa(sa->sin_addr));
ifc.ifc_req++;
}
close(sd);
return 0;
}



Please let me know where i am making a mistake
